Description
Pneumercator MP450S-068-21 Standard Length Stainless Steel Magnetostrictive Rigid Probe for 5’4″ Diameter Tank, Product Gauging with Bottom Water Detection – (SKU: MP450S-068-21) is a standard length rigid magnetostrictive level gauging probe designed for accurate product level measurement and bottom water detection in approximately 5’4″ diameter petroleum storage tanks. It is intended for use in aboveground and underground tanks where continuous level monitoring and water interface detection are required for inventory, safety, and compliance.
Magnetostrictive Product Level Gauging: The MP450S-068-21 uses magnetostrictive technology with a dedicated product float to provide highresolution continuous level measurement over the full probe length. When connected to a Pneumercator TMS series tank monitoring console, it delivers precise product height information suitable for inventory management, ullage calculations, and configurable alarm setpoints.
Bottom Water Monitoring: In addition to product gauging, the probe incorporates a bottom water float positioned near the tank floor to detect accumulated water at the productwater interface. This allows the monitoring system to distinguish between product and water levels, supporting waterintank alarms and maintenance planning to protect fuel quality and downstream equipment.
Standard Length Stainless Steel Construction: The MP450S-068-21 features a 316 stainless steel shaft and compatible float materials for durability in demanding fuel storage environments. As a standard length MP450S series probe it is sized for tanks around 5’4″ diameter and is arranged for installation through a riser or direct tanktop opening using appropriate bushings or flanges.
Typical Applications: This probe is well suited to gasoline, diesel, and other refined product tanks where accurate product gauging and water detection are required in midsized vessels. In combination with a Pneumercator TMS controller, it supports functions such as inventory tracking, overfill prevention, waterintank alarms, and intank leak detection on compatible systems.
Key Specifications: Series MP450S; Model MP450S-068-21; Function Standard length rigid magnetostrictive probe for product gauging and bottom water detection; Technology Magnetostrictive measurement with separate product and water floats plus integral temperature sensing; Materials 316 stainless steel shaft with compatible float options; Mounting Riser or direct tanktop mount through a minimum 2″ opening; Outputs Continuous product level, water level, and temperature signals to Pneumercator TMS consoles.
Summary: The Pneumercator MP450S-068-21 provides standard length stainless steel magnetostrictive product gauging and bottom water detection for approximately 5’4″ diameter tanks in a single rigid probe assembly, making it a strong choice where reliable inventory, water monitoring, and regulatory functions must be handled through one sensor.
